  • Patent number: 11620431
    Abstract: Systems and methods for performing depth-dependent oxidation modeling and depth-dependent etch modeling in a virtual fabrication environment are discussed. More particularly, a virtual fabrication environment models, as part of a process sequence, oxidant dispersion in a depth-dependent manner and simulates the subsequent oxidation reaction based on the determined oxidant thickness along an air/silicon interface. Further the virtual fabrication environment performs depth-dependent etch modeling as part of a process sequence to determine etchant concentration and simulate the etching of material along an air/material interface.

  • Publication number: 20220213884
    Abstract: An electronic angle adjustment mechanism for a pump and a motor generally includes a base and a linear actuator. The base has an upper portion mounted to a motor, a lower portion mounted to a pump, and a hinge for pivotably moving the upper base portion in relation to the lower base portion. The linear actuator is mounted to on an attachment plate that also attaches the motor to the upper base portion. The linear actuator can drive a flexible member or connect to a gear wheel or worm screw to pivot about the hinge and change an angle between the upper and lower base portions.

  • Patent number: 11143172
    Abstract: A liquid pump having a pump liner and a pump piston, wherein the pump liner defines a central longitudinal bore and a transverse inlet bore communicating with the central bore for conveying a liquid. The pump piston has a centerline intersecting with a centerline of the transverse inlet bore, and further has a flat surface formed parallel with the piston centerline at a distal end of the piston. The flat surface defines a cut-out portion of the piston, wherein the cut-out portion has a hydraulic diameter equal to the diameter of the transverse inlet bore of the liner, and a distance from the centerline of the piston to the flat surface defining the cut-out portion is greater than or equal to ½ of the diameter of the transverse inlet bore of the liner.

  • Patent number: 10079280
    Abstract: After forming a first-side epitaxial semiconductor region and a second-side epitaxial semiconductor region on recessed surfaces of a semiconductor portion that are not covered by a gate structure, at least one dielectric layer is formed to cover the first-side and the second-side epitaxial semiconductor regions and the gate structure. A second-side contact opening is formed within the at least one dielectric layer to expose an entirety of the second-side epitaxial semiconductor region. The exposed second-side epitaxial semiconductor region can be replaced by a new second-side epitaxial semiconductor region having a composition different from the first-side epitaxial semiconductor region or can be doped by additional dopants, thus creating an asymmetric first-side epitaxial semiconductor region and a second-side epitaxial semiconductor region. Each of the first-side epitaxial semiconductor region and the second-side epitaxial semiconducting region can function as either a source or a drain for a transistor.
